BARREL-LINING.

SPECIFICATION forming part of Letters Patent No. 591,455, dated October12, 1897. Application filed March 6,1896. Serial No. 582,071. (Nomodel.)

To all whom it may concern:

Be it known that 1, CHARLES E. COTTRELL, a citizen of the United States,residing at the city of Minneapolis, in the county ofHennepin and Stateof Minnesota, have invented certain new and useful Improvements inBarrel-Linings, of which the following is a full, clear, and exactspecification.-

This invention relates to improvements in the art of lining barrels forholding flour and other finely com'minuted dry substances, which, if notleaky between the joints of the staves when first used, are liable tobecome so from the after shrinking of the staves and from the handlingofthe barrels.

Prior to my invention the common practice has been in efforts toavoid'leakage of finelycomminuted substances from a barrel toline thebarrel with overlapping sheets of paper placed therein loosely and insome instances to paste a paper lining throughout the interiorstave-surface of the barrel, but with loose sheets there is a leakagebetween the laps of the paper and considerable inconvenience and anobjectionable loss of time required to place the sheets in positionduring the filling of the barrel, and besides, after the barrel isfilled with the powdered substance there is not sufficient elasticity inthe paper to resist splitting due to the contraction of the staves andthe consequent separation at their joints at the very time when theleakage occurs which said sheets are intended to prevent, and all thisis equally true as to paper pasted upon the staves.

Now the object of my invention is to provide a barrel-lining of such acharacter that it may be readily, quickly, and conveniently insertedwithin the barrel in its operative position and when so inserted willhave no joints opposing the staves through which powdered substances mayescape to the staves and which is so constructed that it may and willexpand and contract with the stave-joints and thereby avoid anypossibility of its cracking or splitting and will effectually preventleakage of the powdered substances between the joints of the staves,however great may be the separation between said joints or howeverroughly the barrel may be handled. This object is attained by devicesillustrated in the accompanying drawings, in which- Figure 1 illustratesa perspective View of a barrel with the head removed and parts brokenaway to show the position of my lining therein. Fig. 2 is a transversevertical section of the barrel and lining. Fig. 3 is a side elevation ofa barrel and packer arranged above the same in its operative positionand having sleeved thereon abarrel-lining embodying my invention. Fig. 4is a vertical section through a barrel and lining of my invention,showing-the ends of the lining folded over across the heads of thebarrel. Fig. 5 is a top planview of the same with the head of the barrelremoved, and Fig. 6 is a transversesection of my lining, showing themanner in which the-vertical edges thereof are interlocked to form atight joint preventing the escape of powdered substances therethrough.

In carrying out my invention I take paper of any length, and preferablyquite a stifi strong Manila paper, and corrugate it transversely of theroll, which corrugated paper is thus cut into suitable lengths, so thatwhen placed within the barrel, with the corrugations thereof runninglengthwise of the barrel, it shall overlap, substantially as shown inFig. 6--that is to say, so that one or more of the corrugations alongthe lapping edges thereof shall be fitted one into the other and by thismeans form an angular joint, preventing the escape ofpowdered substancestherethrough. It will be no departure from my invention, however, tocoil such corrugated strip within the barrel, so as to have two or morethicknesses throughout, nor would it be a substantial departure from myinvention to dispense with this lapping of the corrugations and have thetwo vertical edges of the lining separated from each other when thespace between them is at a point removed from the joint of'a stave, asshown in Fig. 2, when by so doing leakage may be avoided 5 but in prac-'tice I prefer to have the joints lapped and locked together, as beforestated and as shown in Fig. 6.

In the figures of the drawings, A indicates a flour orother barreldesignedto hold finelypowdered substances, B my corrugated liningtherefor, and in Fig. 3. C a packer on which the lining may be sleevedandqtogether with which the lining may be inserted in the barrel in theprocess of filling the same. In thus inserting the lining simultaneouslywithin the contents of the barrel the lining is sleeved over the packerO, as described, and secured thereon in any desired manner, such as bymeans of a simple clamp of any wellknown or suitable construction orother means, and the barrel is then elevated, so as to pass upward overthe packer and the lining, the flour or other material allowed todescend into the barrel, and the packer finally withdrawn, leaving thelining between the barrel and its contents, the corrugations in thelining permitting the latter to expand under the pressure of the flouror contents and to accurately conform to the contour of the barrel. Asindicated at a in Fig. 6, the overlapping joint before referred toisshown, and at Z) the opening between the opposing edges thereof at apoint between the joints of the staves before referred to.

In some instances it may be desirable to make the lining of a sufficientlength greater than the barrel, so that, as indicated at c in Figs. 4and 5, the ends of the lining may be folded over across thebarrel-head-that is to say, partly across, as shown in Fig. at, orentirely across; but as the leakage of barrels containingfinely-powdered substances is at the stave-joints and as such leakagemay be prevented so long as the lining extends throughout the lengths ofthe staves-that is.to say, from head to head-it will be no departurefrom my invention to omit the end folds above referred to.

In practice it is preferred to have the corrugations or flutes in thelining extend lengthwise of the barrel, as shown in the drawings, but itwill be no substantial departure from my invention to use any other formof indentations or folds in the paper which will give the papersufficient elasticity to contract and expand with the contraction andexpansion of the staves to a degree preventing a breaking or cracking ofthe lining and the consequent leakage of the barrel, but in any eventthe corrugations and indentations at the lapping edges of the paper whenlapped as above described should be of such form that the laps will beso locked together as to form a joint tight enough and of such acharacter as to prevent the leakage of the powdered substancestherethrough. Nor would it be any substantial departure from myinvention to paste or otherwise permanently fasten the lining to thebarrel, so long as such pasting or fastening permits the expansion andcontraction of the lining with the contraction and expansion of thestaves to a degree preventing the cracking or splitting of the lining.

By the word corrugation as used in the claims is included fiuting thepaper or otherwise indenting it in any manner that will serve to give itthe expansibility before referred to and permit the edges thereof to belocked together.

The lining thus described maybe composed of any suitable thin materialsuch as Manila paper, as before mentioned, and when used as a lining forflour-barrels it is desirable to use paper tinted with some color thatwill contrast with the flour and thus better display and improve theappearance of the latter when the barrel is open. This is a desirablefeature which will readily be appreciated by those conversant with themanufacture and sale of flour.

In some instances it is desirable to form the lining of waterproof orparaffin paper, which will protect the contents from deterioration bydampness and will be especially useful in the shipment of cement andother like substances, and may be utilized to advantage in the shipmentof drugs and chemicals, which could be packed in wood and provided withthis lining and thus protected from deterioration.

The usefulness of my described lining also consists not only inpreventing leakage of the contents of the barrel or package, but also inprotecting the contents from superfluous and other deleterioussubstances adhering to the inner surface of the barrel, such as charcoalresulting on the inner surface of the barrel, from the latter beingscorched or charred when being heated in the process of manufacture.

My improved barrel-lining is easily inserted into the barrel and may beheld in place by the simple pressure of the contents, or, if desired,may be secured by means of paste touched on a few spots at the time thebarrel is being completed, or the lining may be in .serted at the timethe heading is taken out preparatory to filling the barrel.

It isalso very evident that the exterior of the lining while on thepacker C may be touched ata few spots throughout its surface with asmall quantity of paste and when inserted into the barrel in thedescribed manner the pressure of the contents of the barrel will causethe paste to stick the lining to the barrel, or the interior of thebarrel may be provided at suitable intervals with a small amount ofpaste, and when the lining is inserted over the packer the same resultwill follow.

I am aware that it was not new prior to my invention to form barrels ofcorrugated metal with the corrugations running vertically orlongitudinally of the barrel and stays or ribs located around the barrelin such corrugations and surrounded by hoops to impart rigidity to themetal and prevent the barrel thus constructed from being expanded out ofshape, but the same is not the equivalent of my invention and I do notwish to claim the same, as my invention is materially differenttherefrom in that the corrugated paper which I employ as a lining is alining pure and simple and does not constitute any rigid part of thewalls of the barrel, as does the corrugated metal heretofore used formaking barrels, and consequently in my invention the lining is free toexpand and contract with any expansion and contraction of thebarrel-staves and to automatically conform to the shape of the barreland contents therein, while at the same time constituting an imperviousenvelop for the contents.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. The combination with a barrel, of ayielding paper lining providedwith corrugations of a character to permit said lining to expand andcontract with the expansion and contraction of the barrel-staves andthereby prevent the leakage of powdered substances iherethrough,substantially as set forth.

2. The combination with a barrel, of an expansible lining provided withcorrugated overlapping vertical edges interlocking at their jointureWith each other, substantially as set forth.

' 3. The combination With a barrel, of a corrugated lining adapted toexpand and contract with the expansion and contraction of thestave-joints,which said lining is of greater length than the barrel andis folded over the ends adjacent the heads thereof, substantially as setforth.

4. The combination with a barrel or vessel, of an expansible corrugatedlining arranged therein and being composed of paraflin or waterproofpaper corrugated lengthwise, substantially as set forth.
